Pig suckling stage is a critical period for pig growth. During this period, the piglets grew fast and developed, their metabolism was vigorous, their digestive organs were undeveloped, their digestive function was not perfect, and their innate immunity was lacking. Therefore, most infectious diseases, some parasitic diseases, and nutritional deficiencies caused by improper feeding and management will pose a threat to it, causing morbidity. Many diseases can lead to the direct death of the sow. We compile this group of manuscripts to remind the breeders of the need to strengthen the care for the newborn pigs and increase the survival rate and weaning weight of the pigs.
Rickets
Zigzag disease (croder disease) is caused by calcium or phosphorus deficiency or imbalance in the ratio, and congenital rickets is caused by the lack of nutrients in the sow that causes embryonic dysplasia of the piglet.
At the beginning of clinical symptoms, pigs like to eat mud, dirt, poor growth and development, loss of appetite, rough hair, joints, swelling, swelling, long bone deformation or bone distortion, prone to fracture.
Prevention measures Add a reasonable proportion of calcium, phosphorus and vitamin D to the diet of pregnant sows, and allow them to exercise and sun. In the postpartum sow diet, bone meal, shell powder and other mineral feeds are appropriately added. Let the baby after birth more sun, increase the conversion of vitamin D. For the diseased pigs, 10% calcium chloride injection or 10% calcium gluconate injection may be injected intraperitoneally; calcium lactate or calcium carbonate may be taken orally, and vitamin D may be used in combination. Cod liver oil, calcitriol, vitilin calcium or vitamin AD injection can also be used for treatment.
Blood sugar disease
Clinical Symptoms In general, the piglet develops 2-3 days after birth, often in a litter of several piglets. The clinical manifestations are depression, limb weakness, gait instability when walking, and lying in the ground, showing paroxysmal convulsions, lower body temperature, pale mucous membranes. The eyeball is inactive and mydriasis, but there is still corneal reflex. The mouth is slightly open, and a small amount of white foam flows out. Breathe faster, screaming from time to time, late coma and death. Most of the sick pigs died within 2 hours of onset, and some died after 1 day.
Prevention measures to strengthen the sow's feeding and management, to ensure the normal development of the fetus, postpartum sow's lactation force, to ensure that newborn pigs eat enough milk. Pay attention to keeping the house warm and prevent other stress factors from affecting the pigs. If the sow has no milk, the pigs should be fed manually or fostered in time. The supply of sugar to sows and sows also has a good preventive effect: 50 to 100 grams of sugar per day from 7 days before delivery to 5 days after childbirth; 2% of glucose water is given orally after each birth of a sow. The first 5 ml, 4 times a day, even for 3 days. When a case is discovered, it is treated promptly. It is injected intraperitoneally with 15 ml of 5% glucose solution. It is injected 2-3 times a day for 3-5 days; 20% of a glucose solution is taken orally 20-30 ml and taken 2-3 times a day. 3-5 days. Adrenocorticotropic hormones, such as cortisone acetate injection, may also be administered intramuscularly in an amount of 4 mg/kg body weight of the pig.
Anemia
The clinical symptoms of pigs are generally depressed, body weight loss, weakness, rough coat, dull hair, pale mucosa, breathing, heart rate, a little exercise that is heart palpitations, asthma, like eating bricks, stones, soil, etc. Loss of appetite, constipation or diarrhea, poor growth, etc.
Pathological changes visible mucosa was significantly pale, sometimes mildly yellow, blood thin, such as water, muscle pale, swollen liver, yellowish soil, slightly enlarged spleen, hard texture, heart expansion, gastrointestinal often inflammatory changes.
Control measures 100-500 grams of ferrous sulfate and copper sulfate were added to each ton of feed for pregnant sows. The powder was ground and mixed and fed. In the sheds, often put dried red clay or deep-drying red clay can be eaten, which can supplement iron. Iron supplements were added to the house pigs and supplemented 2-3 days after birth. The following iron preparations can be used for the treatment of piglets: iron-drilling injection, intramuscular injection of 2 to 4 ml for 2 days old piglets; glucose iron and cobalt injection, intramuscular injection of 2 ml for 4 to 10 days old piglets; iron dextran, 3 Day-old pigs were injected intramuscularly with 2 ml.
Hemolytic disease
Neonatal porcine hemolytic disease is an acute, hemolytic disease in which erythrocytes are lysed by neonatal pigs eating colostrum. The piglets are characterized by anemia, jaundice and hemoglobinuria, with a lethal rate of 100%.
Disease factor Pig parents have blood group incompatibility. The pig inherits the red blood cell antigen of the father and livestock. This antigen enters the maternal blood circulation during pregnancy, and the sow produces specific blood group antibodies that are resistant to the porcine erythrocytes. This antibody molecule cannot pass through the placenta, but it can be secreted in colostrum. The pigs suck colostrum containing high concentrations of antibodies. After absorption by the gastrointestinal tract, the antibody binds to specific antigens on the surface of red blood cells and activates complement, causing acute intravascular hemolysis. .
After the birth of the pig, there was no abnormality in the condition of nyphorodynia and spirit. However, the onset of disease was 2-10 hours after sucking sow's colostrum. Symptoms were cessation of milk supply, mental euphemism, chills, general tremors, coarse hair disorder, Standing, the hindquarters sway, the conjunctiva and gums are stained yellow. In severe cases, even the black piglets, the skin can be dyed yellow, the stool is thin, the urine is transparent red or dark red, the body temperature is 39°C-40°C, disease The pig died after 1-2 days.
Prevention and treatment measures There are no specific treatments for this disease. If the newborn pigs are found to be hemolyzed, they should immediately stop feeding in the original litter. They can be transferred to nursing sows fed by other boars to avoid hemolysis.
Weakness
After the birth of the pig, the child is stunted. The individual is shorter than the normal pig, weak, inactive, limbless, walking, shaking, mental fatigue, poor appetite, even unable to hold the nipple, unable to suck the milk. Some are susceptible to colds, pneumonia, diarrhea and other diseases, and some die within a few days after birth.
Prevention and treatment measures have no specific treatment for this disease. In production, the following measures can be taken to prevent: to strengthen the feeding and management of pregnant sows, especially for the late sows, to provide nutritious feed, especially protein, minerals and vitamins must be sufficient. Establish public and sow pedigree cards to prevent inbreeding, prevent premature breeding, and eliminate outdated male and female sows in time.
White muscle disease
Causes of Disease Pigs Selenium-deficient or vitamin E alone can cause white muscle disease, which is generally caused by a serious lack of both selenium and vitamin E. If the amount of selenium in the feed is insufficient, vitamin E is sufficient, and selenium deficiency can be compensated. If both are insufficient, the symptoms of selenium deficiency are revealed. Therefore, the supply of vitamin E plays an important role in the occurrence of this disease. The disease usually occurs in 2-3 months, because the spring is the season of sow pregnancy and childbirth, and the disease is mainly inflicted on newborn pigs, so the formation of spring is the season of sow pregnancy, childbirth, and the disease is mainly infringed Newborn pigs, thus forming a spring peak. The earliest disease can occur during the embryonic period, resulting in premature sows, stillbirths or abortions. During the development of the fetus, especially the late fetal development, due to lack of nutrient supply, leading to the onset of nutritional loss and disease.
Sudden onset of clinical symptoms, manifestations of lack of energy, loss of appetite, rapid weakness, difficulty breathing, sudden death. Longer duration, manifested as strong hind limbs, arched backs, difficulty standing, some standing legs or dogs sitting, severe limb paralysis, lying in the ground, difficulty in sucking and sucking, weak heart, and finally died, the course of the disease is generally 3-8 days.
Symptoms of the necropsy found skeletal muscles, especially the muscles of the buttocks and back, were degenerated, showing grayish or gray-yellow stripes. Pericardial effusion, increased cardiac capacity, pale gray or pale white spots on the endocardium, marked weakness of the myocardium, ring death, and macular hemorrhage in the endocardium and adventitia.
Prevention measures: Sodium selenite can be added to the feed of pigs, and 0.1-0.2 g per ton of feed is used for prevention. In winter, pregnant sows can be given a subcutaneous register of 3-5 ml of sodium selenite 0.1%, once every 20 days, for a total of three injections, and vitamin E injections. After the pig is born, it is given intramuscular injection of 0.1% sodium selenite 10 ml, vitamin E 50-75 ml, and cod liver oil 3 long.
Congenital tremor
Congenital tremors of piglets mainly occur in newly born piglets, with clinical features of rhythmic tremors in the extremities, head, or body. Adult pigs are occult or chronically infected.
Epidemiological features The disease spreads through vertical transmission. It only infects pigs and is susceptible to different breeds and their offspring. There was no obvious seasonality, and there were multiple precocious sows and very few sows. The disease was sporadic. The mortality rate of each epidemic was 10%-30%. Rehabilitation pigs often become carriers of virus, and boars can be infected with sick gilts and become infected pigs.
After the clinical symptoms of pigs are born, the main manifestation of skeletal muscle rhythm earthquake. Tremors are generally bilateral, occurring mostly in the head and extremities. Severe persons may see body shaking. Due to the intense and rhythmic bursts of sputum, the piglets inadvertently jump up and down when standing and walking. This phenomenon disappears temporarily when the pig is lying. As the pigs indiscriminately jumped, the progress was difficult, and it caused inconvenience to the milk. They often starved to death because they couldn't hold the nipples.
Preventive measures to strengthen the feeding and management of pregnant sows, to provide nutritious full-priced feed. Do not introduce breeding pigs from a farm with this disease. There is no specific treatment method for the affected pigs. After the onset of the pigs, care should be taken to allow them to eat colostrum so as to prevent the pigs from becoming hungry. If they are properly cared for, the disease can be cured.
False death
Prenatal intense tossing of sows can lead to premature discontinuation of the umbilical cord or separation of the mother and child placenta. The narrowing of the sow's birth canal or improper fetal position that results in a long fetal delivery time for the umbilical cord may result in the production of asphyxial pigs. Some of them can not breathe but the heart is still beating, with the finger gently press the umbilical cord root can touch the pulse, this is a fake pig.
Symptoms of bodily death are usually pale skin, immobile limbs, and no breathing, but there are still heartbeats.
Prevention and control measures During the delivery of sows, we must do a good job of artificial midwifery to minimize the sow's production process and prevent the suspended life of the pigs. For the fake baby to be rescued in time, the specific approach: First, wipe the mucus of the pig's nose and mouth, and then artificial respiration. If you use your left hand to lift the pig's two hind legs, the right hand beats the back of the pig rhythmically until the pig makes a call. It is also possible to hold the pig's shoulder and back in one hand, hold the pig's back buttocks together with the hind limbs, and then stretch it repeatedly to help it recover. You can also wipe your nose and mouth with iodine or alcohol to stimulate your breathing.
